The perfect fuel tap for those fitments with clearance issues, the main square body measures only 18mm, with a lever length of 38mm. The outlet spigot measures 5/16" O.D. with a 3/16" bore flow. ......ON / OFF ...NO reserve

Adapters are available for 57-74 & 75 up Harley tanks in our ebay shop

(( Or chase through with a NPT machine tool tap...as it is very...very close to that thread ))

We have also found some tanks may need deeper thread taping out to acheive more than a couple of rotations in. I have a listing for our machined weld on bungs, which will use up around 3/4 of the thread length.
